Answer:she has 120 apples left.
Step-by-step explanation:
Total number of apples that Lexi had in her basket to sell is 300.
If she dropped 122 apples on the ground because she can't use them and sell them, then the number of apples that she has left for sale is
300 - 122 = 178
If then after she sells 58 apples, the number of apples that she has remaining would be
178 - 58 = 120 apples
